CSFlow: A Content-Aware Secure Flow Control System for Encrypted Data Sharing in Cloud-Edge

CSFlow is a system designed to control how encrypted data (data that's been scrambled so only authorized people can read it) is shared across cloud and edge computing environments (distributed computing systems with servers in different locations). Unlike older systems that only check who is allowed to send and receive data, CSFlow also examines the actual content of messages to prevent authorized users from illegally sharing sensitive information by adding content tags and sender policies to encryption keys.
